pch=strstr?

Good Day:
I have included pch=strstr (input1, 'good'); in my code, but I am receiving erorrs O' plenty; the code is supossed to detect a selected word ('good', for example) from a string and return it, I would think, to be stored in an array for use as a trigger in a following, Boolean function. Do I need to include a pointer such as, pch * strstr (input1, 'good') the variable being char*str[]="good"; ? I am not sure, but I know something is incorrect. Any suggestions would be greatly appreciated ...
thank-you,
